The Twin Air Pre-Oiled Air Filter, part number 154119DRX, is designed for riders who demand dependable engine protection in motocross and off-road conditions. This replacement foam air filter is pre-oiled with Twin Air biodegradable foam filter oil, developed exclusively for Twin Air by Chevron Texaco. The specialized oil formulation helps capture contaminants while maintaining efficient airflow for consistent engine performance.
Featuring a dual-layer foam design, the filter uses coarse open-pore outer foam to catch airborne dirt, grime, and sand before they reach the engine. Fine open-pore inner foam provides a second filtration stage that traps smaller particles while supporting maximum air passage. The filter’s adhesive is engineered to withstand repeated cleaning, making it a practical choice for regular maintenance and demanding riding environments.
Its smaller-than-stock profile increases air space and circulation around the filter, helping promote effective airflow within the airbox. The Twin Air filter is built as a direct-fit replacement for select KTM Factory Edition motocross models and is suitable for riders seeking reliable filtration without unnecessary modifications.
Fitment: Fits 2026 KTM 450 SX-F Factory Edition and 2026 KTM 250 SX-F Factory Edition. Manufactured by Twin Air and identified by manufacturer and vendor part number 154119DRX.
